THEODORE A. BLAKE, OF NEW HAVEN, CONNECTICUT.

PIG-IRON BREAKER.

SPECIFICATION forming part of Letters Patent No. 256,960, dated April25, 1882.

Application filed January 16, 1882. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE A. BLAKE, of New Haven, in. the county ofNew Haven and. State of Connecticut, have invented a new Improvement inMachines for Breaking Pig-Iron; and I do hereby declare the following,when taken in connection with accompanying drawing and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawing constitutes part of this specification,and represents a vertical sectional view.

This invention relates to an improvement in the machine for breakingpig-iron for which Letters Patent were gran ted to me dated May 3, 1881,No. 240,951.

In my previous patent the machine consists essentially of an anvil, overwhich the pig is placed to be broken, and a reciprocating slide above,carrying two breaking-points, one in front and the other in rear of theanvil, so as to strike upon the top of the pig each side the anvil andforce it downward, breaking it over the anvil.

I have found from experience that sometimes the pig will be arrangedover the anvil so that the outer breaking-point will strike close totheend of the pig, and then, as the force is applied, that breaking-pointtends to glance outward over the end of the pig, and thus bring atransverse strain above the breaking-point, which sometimes breaks it;or the same kind of strain is brought upon either of the breaking pointswhen they come upon any irregularity in the surface of the pig, and thisirregularity may-tend to force them in either direction, out or in,according to the way in Y which the irregularity is presented to them.

The strain produced always tends to break the points.

The object of my invention is to overcome this difficulty; and itconsists in providing one or both of the breaking-points with anindia-rubber seat or hearing which will yield to the transverse strainbrought upon it, as more fully hereinafter described.

In the drawing I illustrate only the anvil and a reciprocating slide,which carries the two breaking points or blocks, that being suflicientfor the illustration of my invention.

A represents the bed upon which the anvil a is arranged, and upon whichthe pig is placed to be broken. slide, arrangedto be moved up and downin suitable guides from and toward the anvil. Upon its under side it isfitted with two breakin g points or blocks, 1) d, one each side'that is,in front and rear of the anvilso that the pig lies on the anvil, asindicated in broken lines. When the slide descends it will bring the twoblocks 1) d to a bearing upon the upper surface of the pig, one eachside of the anvil, andthen, forced down ward, will break the pig acrossthe anvil. This is substantially like the device shown in my previouspatent.

Instead of making the blocks rigid upon the slide or head B, I make arecess in the head outside the block, and into that place a spring, 0,of india-rubber, against which the hammer will firmly hear. The force ofthe spring may be adjusted by a set-screw, 1''. By this improvement,when the slide descends the transverse strain which is brought upon theblocks, tending to throw them outward or inward, will be received by thesprings e, and they, yielding, will permit the block to move with orupon the parts of the pig, and thus avoid the transverse or breakingstrain heretofore experienced in my pig-iron breaker.

If one of the blocks only be provided with a spring, it will accomplishthe object but both may be, and in some cases would be better, providedwith the rubber.

The rubber may be arranged on the opposite side of the hammer-as, forinstance, as indicated at h; but I prefer to arrange the spring upon theoutside.

As stated in my patent referred to, it will be understood that the anviland breaking point or block may be reversed, the single breaking-pointbeing above and the other two below, without departing from myinvention.

I claim- In a pig-iron breaker, the breaking block or blocks providedwith a rubber spring to receive the transverse strain produced inbreaking the pig, substantially as described.
